Orthodontic patients usually replace 30 to 40 pairs of aligners during their entire treatment—to achieve the best result. Every pair features small incremental changes in the aligner. Compared to traditional manufacturing methods, stereolithography technology currently enables customization and mass production at a high resolution, with a high surface quality. The stereolithography process is used to build tooling based on CAD data for a secondary thermoforming of the actual aligner. Smartee Dental chose UnionTech™ stereolithography equipment after a detailed investigation and comparison of various 3D printing technologies.
“Relative to cost effectiveness, accuracy, efficiency, stability, and safety, Stereolithography is the best choice. It is also very important to our production stability and product performance that occasional equipment maintenance issues are addressed in a timely manner. UnionTech™ has provided us with great after-sales service and is responsive to our feedback regarding desired technology improvements, ” continued Mr. Jun Feng Yao.
